Specification of Letters Patent.

Patented Feb. 16, 1915.

Application filed July 24, 1914. Serial No. 852,860.

To all whom it may concern Be it known that I, BOULTBEE BROOKS, subjectof the King of Great Britain, residing at Criterion Works, Great Charlesstreet, Birmingham, England, have invented certain new and usefulImprovements in Cycle, Motor-Cycle, and Analogous Saddles and Seats, ofwhich the following is a specification.

This invention relates to cycle, motorcycle and analogous saddles andseats of the type comprising a rigid seat top supported at its rear endby a system of springs connected to or operated by a radius rod ormember arranged beneath the seat top and hinged at its forward end tothe base bracket, so as to prevent displacement of the rear springs fromtheir normal line of action or are of movement and thus insure the mostefiicient working of said springs under all conditions and with therider seated in any position upon the saddle, either forward or rearwardof the normal position.

The object of the present invention is to provide means for resilientlysupporting the peak or front portion of the above type of saddle whileretaining all the advantages referred to attendant upon the use of theradius rod.

The invention consists in hingedly mounting the rigid seat top at itsrear end upon the radius member (which is in the form of a supplementaryunder seat-frame) and interposing a spring or springs between the saidseat top and the radius member in order to resiliently support the frontof the seat, a suitable stop device being provided, if necessary, forlimiting the relative vertical movement between the said seat and baseframe. The radius member or supplementary seat frame, being directlyconnected between the front of the base frame and the hanger rods whichoperate the rear springs, prevents distortion or angular displacement ofthe said springs, while the seat, being hingedly mounted upon thesupplementary frame, acts as a radius rod for preventing distortion ordisplacement of the front spring, especially when the latter is of thecoiled type.

Figure 1. of the accompanying drawings represents a side elevation of amotor-cycle saddle constructed in accordance with this invention. Fig.2. is a longitudinal section through the said saddle showing the frontspring compressed. Fig. 3. illustrates a vertical section on line X,Fig. 1. Fig. 4. is a front View of the peak of the saddle, showng thestop arrangement employed in conunction with the front spring. Fig. 5.shows an underside plan of the saddle. Fig. 6. is a section showing howthe seat top is hinged to the supplementary under frame. ig. 7.represents a sectional side elevation of a modification. Fig. 8.illustrates an underside plan of this modification. Fig. 9. is a topsideplan showing how the leaf spring bears upon the supplementary underframe. And Fig. 10 shown a side elevation of a further modification inwhich loop coilsare used instead of pivots for connecting the seat topto the radius member.

eferring to Figs. 1 to 6, hinged at one end to the forward extremity ofthe usual base bracket 1. of the saddle is a supplementary seat-frame orradius member 2. which is forked or divided at about its middle and thepair of arms or branches spread out laterally, their extremities beingprovided with bent-up ears 3. by which they are jointed at 4 to lugs 5.carried upon each side of the seat-plate 6. which is bolted or otherwisefixed to the underside of the rigid seat top 7. in the usual manner. Theextremities of the said arms or branches of the frame 2. also carrydepending hanger rods 8. connected at their lower ends to coiled springs9. (preferably of the compound tension and compression type) suspendedfrom the base bracket 1. Inter-posed between the said supplementary orunder seat frame 2. and the underside of the seat plate proper 6, at theextreme peak of the saddle, is a coiled spring 10, and in order to limitthe vertical movement of the seat top 1. a stop device is providedcomprising a depending front plate 11. carried by the seat plate 6. andprovided with a vertical. slot 12. engaged by a lug 13. carried by abracket 14. fixed to or formed out of the forward end of the supplementary frame 2. On the peak or forward end of the saddle beingforced down ward the spring 10 is rendered active and absorbs any shockor vibration and prevents same from being transmitted to the rider. Ifdesired the slotted part may be carried by the frame 2. and the engaginglug by the seat top.

In the modification represented in Figs. 7 to 9, instead of the peak ofthe saddle being supported by a coiled spring, there is interposedbetween the frame 2. and the underside of the seat plate 6. a centrallyand longitudinally disposed laminated leaf spring 15. The rear end ofthe said spring being fixed to the seat plate 6, while its forward endis arranged to bear upon the forward part of the supplementary frame 2.In order to form a stop device for limiting the vertical movement of.the seatv 7. the plate 6. is provided upon its underside and preferablynear its forward end, with a pair of laterally separated depending ears16. to which are jointed a pair of links 17. whose ends are arranged tocome one upon each side of the supplementary frame, the

said ends being formed with longitudinal slots 18 which are engaged bythe ends of a transverse pin 19 carried by and fixed to the said frame2. Also, as shown in Fig. 10, instead of pivots being employed forhinging the seat top 7 to the radius member 2. loop coils of wire 20 maybe used. Any other suitable form of stop device may be employed forlimiting the relative vertical movement between the seat plate and basebracket.

Having fully described my invention, what I desire to claim and secureby Letters Patent is 1- 1. A motor-cycle, cycle or analogous saddle orseat comprising a base framing, a rigid seat top, a supplementary underseat frame separate from the seat top and directly hinged to the frontof the base framing, said seat top being hinged at its rear end to thesupplementary seat frame, depending hanger rods carried by the latter,coiled springs suspended from the base framing and connected to thelower ends of the hanger rods,

Copies of this patent may be obtained for and springs interposed betweenthe seat top and the supplementary seat frame.

2. A motor-cycle, cycle or analogous saddle or seat comprising a baseframing, a rigid seat top, a supplementary under seat frame separatefrom the seat top and directly hinged to the front of the base framing,said seat top being hinged at its rear end to the supplementary seatframe, rear load-supporting springs connected to the said supplementaryseat frame and to the base framing, a resilient device interposedbetween the seat top and the supplementary seat frame, and a stop devicefor limiting the upward movement of the seat top relatively to the saidsupplementary seat frame.

3. A motor-cycle, cycle or analogous saddle or seat comprising a baseframing, a rigid seat top, a supplementary under seat frame separatefrom the seat top and directly hinged to the front of the base framing,said seat top being hinged at its rear end to the supplementary seatframe, rear loadsupporting springs connected to the said supplementaryseat frame and to the base framing, a resilient device interposedbetween the seat top and the supplementary seat frame, and a stop devicefor limiting the relative movement between the seat top andsupplementary seat frame comprising a slotted member carried by the onepart engaged by a projection carried by the other part.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
